Question

我正在尝试将python的pip从19.3.1版本升级到20.0.2。 Python版本3.8 当我输入"python -m pip install --upgrade pip"更新点时，我得到的只是错误消息：

"ERROR: Exception:

AttributeError: 'NoneType' object has no attribute 'bytes'
WARNING: You are using pip version 19.3.1; however, version 20.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command."

我尝试手动更新pip，重新安装到python 3.8.2的最新版本，卸载python，然后再次安装。没有成功。 Pip也没有安装新软件包。我希望我已经为解决问题做好了准备。

更新点时出现错误。如何正确更新点数？
